Mars Science Lab's Two Year Journey

·     

           

(A) Curiosity will trundle around its landing site looking for interesting rock features to study. Its top speed is about 4cm/s

·         (B) This mission has 17 cameras. They will identify particular targets, and a laser will zap those rocks to probe their chemistry

·         (C) If the signal is significant, Curiosity will swing over instruments on its arm for close-up investigation. These include a microscope

·         (D) Samples drilled from rock, or scooped from the soil, can be delivered to two hi-tech analysis labs inside the rover body

·         (E) The results are sent to Earth through antennas on the rover deck. Return commands tell the rover where it should drive next
